Are you drunk or high when you babble like this? Does the guy you see in the mirror understand and agree with you?
Let me dumb it down for you, toodles: Dump & company's idea of America's former "greatness" doesn't address or acknowledge (or give a damn) that it wasn't so "great" for large portions of the population. Hell, the Native Americans haven't had it "great" on the whole since your ancestors should up on the shores a few centuries ago. History has proven that.
This is why the OP strikes a nerve with dullards like you, because you just don't have the intellectual or moral courage to deal with the full history of America. This is why you babble the jingoistic BS that you do....a perfect, predictable answer to the OP from the likes of you. Carry on.
